Prediabetes, insulin and weight: how they connect

In short

With prediabetes, blood sugar is raised but not yet in the diabetes range. Insulin resistance is often behind it: cells respond less to insulin, so the pancreas has to release more.

Lifestyle changes with exercise, a balanced diet and, where needed, weight reduction can clearly lower the risk of type 2 diabetes, as large prevention studies show.

What insulin has to do with weight

Insulin moves sugar from the blood into cells and promotes energy storage. Belly fat in particular is closely linked to insulin resistance: it is metabolically active and can worsen insulin action further.

That easily becomes a cycle. Higher insulin levels make fat storage easier, and more belly fat increases resistance. The good news: even moderate changes can slow this cycle.

What you can do

  • Move regularly; short walks after meals count
  • Build muscle, because muscles use sugar
  • Swap sugary drinks for water or unsweetened tea
  • Choose wholegrains, pulses and vegetables over white flour
  • Get enough sleep
  • Have your blood sugar checked regularly, e.g. HbA1c

What about medicines?

Prediabetes alone is not an approved indication for weight-management medicines. If overweight with related conditions or obesity is also present, GLP-1 treatment may be an option. Whether that applies to you is assessed in the medical review of your questionnaire.
